That phrase--"the only good _______ is a dead one"--has been overused in many contexts to the point that I just can't be bothered to care about anyone using it anymore. When you think of something more outrageous and less cliché, let me know.

Why on Earth would any sane person pick a screen name that was the code name for a covert CIA mind control and chemical interrogation program? That alone should tell us more about this guy than anything he might post in a forum.
